WINDHAM — A gas leak on Tuesday prompted the evacuation of at least 20 percent of the buildings on the campus of Eastern Connecticut State University, according to school officials.

Jim Howard, vice president of finance and administration for the university, said a crew struck a small gas line on Windham Street while working on a sidewalk and streetlight beautification project. Howard said the leak led the university to evacuate buildings in the area of the leak, which he estimated to be about 20 percent of the buildings.

"Luckily, we don't have a lot of students on campus this time of year," Howard said.

Yankee Gas said they received a report of an equipment issue at ECSU around 11:30 a.m.
